Joseph Coradino, CEO of the Philadelphia-based mall owner and operator listed the Palmer Township mall on a list of five shopping centers the investment trust hopes to sell this year, in an announcement touting the sale of $192 million worth of assets in 2014.

"By proactively marketing additional assets for sale in 2015, we are confident that we are taking the right steps to continue a portfolio transformation that will set us apart from our peers while generating significant proceeds to further upgrade our core, high-quality properties," Coradino said.

The company, which also owns a portion of the Lehigh Valley Mall, has pursued a strategy of selling its underperforming malls in order to pump money into upgrading its top-grossing properties.

Last month, it sold its 50 percent interest in the Whitehall Mall for $25 million, packaged with two smaller commercial properties, and in June sold the South Mall on the Allentown-Salisbury Township border for $23.6 million.

Since 2012, the PREIT has sold 16 assets including six enclosed malls generating average sales per square foot of less than $250, for a total of $424.1 million, the trust said.

It owns and operates 29 million square feet of space in properties in 12 states in the eastern U.S., primarily the Mid-Atlantic, including the Willow Grove, Cherry Hill, Plymouth Meeting and The Gallery malls in the Philadelphia area.

The four other malls up for sale in 2015 are the Uniontown Mall in Uniontown, Lycoming Mall in Williamsport, Washington Crown Center in Washington and Springfield Park in Springfield, Delaware County.
